I have owed a set of these sticks for the last 2 months now and they are holding up very well. the only problem i have with these sticks is the fact that they seem to be lighter than wooden sticks even with the rubber core inside to add weight. they chip a lot more than wooden sticks and the chips are dark so they are easily noticed on my kit. I love the feel of these sticks even with some of the bad press Millenium get for there products. they are a cheaper alternative to the Vic-Firth version however when my set eventually break i plan on getting a set of the Vic-Firths for comparison. The area that is held in the players hand is not worn down or has gone shiny from using them which means that your grip will always feel strong when playing with them. i have put these sticks through the test of my play style and the only thing that comes out damaged is me!!!
